In many temperate-zone ecosystems, seasonal changes in environmental and biological factors influence the dynamics and magnitude of surface-atmosphere exchange. Research was conducted August 2019 to measure surface-layer fluxes of CO2 in a Bogd khan mountain, Uvur zaisan valley. Soil-surface CO2 fluxes were measured with a closed-chamber system. The ranges of measured soil-surface CO2 flux were 312-856 ppm CO2 0.0314 m2 10 min. Soil-surface CO2 fluxes averaged 560.5 ppm CO2 0.0314 m2 10 min. Study showed that there was a significant relationship between flux and temperature (R2=0.79).
